Hi,
I have a problem with VFB. When I start render and I click on VFB while rendering, VFB window and Rendering window freeze for 4 or 5 seconds or so. It happen every time I only click on VFB, so its hard to make any changes in color corrections or scale a window for example. But this happen only in standard rendering, thank god IPR is not affected. And in newest VRay Next SP2 only (I test max 2019 and 2020 with same result), SP1 didnt do that at all.
Have you made any changes to the 3ds Max process priority somehow? For this update, we reduced the priority of the rendering threads internally to prevent other UI issues.
Best regards,

No, I didnt change max priority. Sometimes I only disable some threads from process, but it doesnt matter in this case. It happen every time 
Is there something I can try in some windows settings or anything please?
Hmm, this is bad. I wanted to zoom in VFB while standard DR rendering, expect small lag in update 2, but after large lag max crash
So its happening only when both computers use DR. When I use DR on second and Use Local Host on main computer, its ok.
Ok, that’s a pointer. Can you send me a crash dump to vlado@chaosgroup.com ? This is the file 3dsmax_minidump.dmp from your temporary folder (type %temp% in Windows Explorer to go there)?
Best regards,

I think I dont have it, max crashed one or two times after that. Only lag for 5 seconds or so remain, no crash after last time.
Ok, if it happens again, the crash minidump will be useful.
Best regards,
Vlado
I think it was one of those crashes without the message about the max crash and minidump file, so I dont know if minidump was created. But yeah, if that happen again, I definitely look at this.
